Personally I'd be all for some sort of general football register/Council/whatever like you see in other professions.
Teachers, doctors, nurses, engineers, accountants etc etc can all be struck off and banned from practicing for those sort of offenses. I see no reason why footballers shouldn't be held to similar standards.
It might even have a positive effect on the game if some of the more colourful ( arseholey) players knew they could lose their career and were forced to focus on their football.
